Currently away with Mali at the African Cup of Nations, it has been reported by Portuguese media that Marega has told those close to him that he no longer plans to return to FC Porto.
The 28-year-old who has never hidden his desire of playing in the Premier League believes that his dream is about to come to fruition.
Rival Premier League clubs Aston Villa and Wolverhampton Wanderers are also said to be in the race to sign the striker.
West Ham have thought to have scouted the FC Porto forward for some time but have previously put off by the £40m valuation put on his head by the Portuguese club.
